As Toro Y Moi, Chaz Bundick has gone from making murky, queasy bedroom-pop to crafting slick, twitchy soul. There’s plenty of room for experimentation and change in Toro Y Moi, then, but there’s not quite enough for Bundick. He’s got a whole other alias as Les Sins, the alter-ego he’s used to release a few instrumental dance singles over the year, the most recent of which, “Grind” b/w “Prelims,” dropped last year. Later this year, Bundick will release his first full-length album as Les Sins. It’s called Michael, and it’s almost completely instrumental, though Californian singer-songwriter Nate Salman does guest. The first single is an idiosyncratic quicksilver piece of house music called “Bother,” and you can hear it below.
